I have a GO and am pleased with it but I think if it were to break I might consider replacing it with the Sizzix because of it does cut more layers at one time and the cost of the dies seems to be more reasonable. But, I would look into it more thoroughly if that time came. I have quite a collection of GO dies and I do understand they can be used on the Sizzix with some sort of adapter. I guess the only drawback I see is the fact that the big shot pro is similar to the Accuut Studio, meaning it is a stand alone and must have a dedicated place...whereas the GO is portable..oh well just thinking out loud....
